Animals that do not have red blood
Ice crocodile fish
Crocodile Icefish is characterized by its colorless blood, as it does not contain hemoglobin, and this fish lives in the vicinity of Antarctica. Since the cold water is rich in oxygen more than warm water, this fish absorbs oxygen directly from the ocean water and transports it For its bloodstream without the need for the presence of red blood cells, and this was proven by the biologist Ditlef Rustad in 1928 when he dissected one of these fish, as Rostd explained that the absorption of oxygen in the cold water of the ice crocodile fish does not need the presence of red blood cells to move between The cells of the body of this fish.
Octopus belongs to invertebrate animals and is characterized by the blue color of its blood because its blood contains hemocyanin instead of hemoglobin. In contrast, hemoglobin contains iron atoms; hemocyanin contains copper protein, which is why the blue blood in octopus When the blood is mixed With the oxygen resulting from transporting the oxygen to the bloodstream of the octopus, the copper turns blue. It is worth noting that the octopus uses the protein that contains copper to maintain its life in deep and cold sea environments.
